In a particular month, Ezhil spent one-fifth of her salary on shopping. Two-fifth of the remaining she gave to her sister. If sh

Oxana [17]

Answer:

$Salary = Rs23000$

Step-by-step explanation:

Given

$Shopping = \frac{1}{5}$

$Sister = \frac{2}{5}R$

$Left over = Rs11,040$

Required

Her salary in that month

Given that she spent $\frac{1}{5}$ of her salary on shopping, this implies that she has $\frac{4}{5}$ of her salary left

From what's left, she gave her sister $\frac{2}{5}$

This means she gave her sister $\frac{2}{5} * \frac{4}{5}$

Sister = $\frac{8}{25}$

Calculating a fraction of what's left

$Left over = 1 -Shopping - Sister$

$Left over = 1 - \frac{1}{5}- \frac{8}{25}$

$Left over = \frac{25 - 5 - 8}{25}$

$Left over = \frac{12}{25}$

Recall that she has Rs11,040

This means that

$\frac{12}{25} of Salary = Rs11,040$

Multiply both sides by $\frac{25}{12}$

$\frac{12}{25} * \frac{25}{12} * Salary = Rs11,040 * \frac{25}{12}$

$Salary = Rs11,040 * \frac{25}{12}$

$Salary = \frac{Rs276000}{12}$

$Salary = Rs23000$

Hence, her salary for that month was Rs23000

What equation represents the function on the graph

zloy xaker [14]

Answer:

cos 4x

Step-by-step explanation:

Because this graph begins at (0, 1), we immediately suspect that it's a cosine function. Additionally, since there are 4 cycles of this cosine function between x = 0 and x = 2pi, we suspect horizontal compression:

Eric was rock climbing. At one point, he stopped and climbed straight down 2 1/2 METERS

sasho [114]

Answer:

$+4\frac{1}{4}$ meters

Step-by-step explanation:

Let's take climbing down as "negative" and climbing up as "positive". Now, we can simply use the numbers and signs to find the change in elevation.

$2\frac{1}{2}$ meters down means $-2\frac{1}{2}$
$6\frac{3}{4}$ meters up means $+6\frac{3}{4}$

So, now we have: $-2\frac{1}{2}+6\frac{3}{4}\\=-\frac{5}{2}+\frac{27}{4}\\=\frac{-5(2)+27}{4}\\=\frac{-10+27}{4}\\=\frac{17}{4}=4\frac{1}{4}$

<u>Eric's elevation changed $4\frac{1}{4}$ meters above. So after the 2 moves, he is up by $4\frac{1}{4}$ meters.</u>
